Question

Ammonium perchlorate nh4clo4 is a powerful solid rocket fuel, used in the space shuttle boosters. it decomposes into nitrogen n2 gas, chlorine cl2 gas, oxygen o2 gas and water vapor, releasing a great deal of energy. calculate the moles of ammonium perchlorate needed to produce 1.4 of nitrogen. be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

Answer:

Explanation:

2 NH₄ClO₄ ⇒ N₂ + Cl₂ + 2O₂ + 4 H₂O

2 moles          1 mole

We are required to produce 1.4 moles of N₂ from ammonium perchlorate .  

1 mole of N₂ is produced by 2 moles of ammonium perchlorate

1.4 moles of N₂ will be produced by 2 x 1.4 = 2.8 moles of ammonium perchlorate .

Answer is 2.8 moles .
